Q&A
Can I use this mod in my modpack?
- Absolutely! Credit is appreciated. Can I use this addon in my public server?
- You may under the condition that none of the content in this mod is locked behind a paywall of any kind. This includes lootboxes that can be purchased with real money, even if the player can earn them for free.
Where are they?? 😭
- All Glitchmon can spawn in the Nether at Y-levels greater than 110. I'd advise clearing out a large area to give them room to spawn.
- MissingNo. and 'M can spawn at beaches, although extremely rarely.
Where is my GOAT [insert Glitchmon here]?
- There's a lot of Glitchmon out there, and I can't realistically add every single one. I will only add glitches that are not hybrids of other Pokemon, and are not clones of *other* Glitchmon.
- Glitchmon clones are combined together into one fakemon.
- 'M is the exception to this, as it is too iconic.
Credits
- All modeling, spritework, and sound design was done by me.
- Bulbapedia, for providing information about these glitches.
- Sounds Resource and Freesound for providing sounds used to create the cries.
